The Fengxiang East Lake Garden was created by Su Dongpo and was recorded in the Guanzhong Scenic Spots as early as the Qing Dynasty. It enjoys a high status in the northwest gardens of China. Later generations referred to it as the sister lake along with the West Lake in Hangzhou, which is a typical case of Su Dongpo’s early garden construction ideas. This “literati” approach to garden construction, which emphasizes the mountainous and water environment and artistic conception, is of great significance for revealing the study of the gardening theory of local gardens in the northwest.
